Rechargeable zinc–air batteries are widely recognized as a highly promising technology for energy conversion and storage, offering a cost‐effective and viable alternative to commercial lithium‐ion batteries due to their unique advantages. However, the practical application and commercialization of zinc–air batteries are hindered by the sluggish kinetics of the oxygen reduction reaction (ORR) and oxygen...
The highest specific energy absorption (SEA) of interlocked micron‐thickness carbon nanotube (IMCNT) films subjected to micro‐ballistic impact is reported in this paper. The SEA of the IMCNT films ranges from 0.8 to 1.6 MJ kg−1, the greatest value for micron‐thickness films to date. The multiple deformation‐induced dissipation channels at the nanoscale involving disorder‐to‐order transition, frictional...
Nanotechnology employs multifunctional engineered materials in the nanoscale range that provides many opportunities for translational stem cell research and therapy. Here, a cell‐penetrating peptide (virus‐1 transactivator of transcription)–conjugated, porous silicon nanoparticle (TPSi NP) loaded with the Wnt3a protein to increase both the cell survival rate and the delivery precision of stem cell...
Phototherapy is a promising treatment method for cancer therapy. However, the various factors have greatly restricted phototherapy development, including the poor accumulation of photosensitizer in tumor, hypoxia in solid tumor tissue and systemic phototoxicity. Herein, a mitochondrial‐targeted multifunctional dye‐anchored manganese oxide nanoparticle (IR808@MnO NP) is developed for enhancing phototherapy...
A novel unidirectional liquid spreading surface with an inclined arc pitted groove, inspired by the continuous unidirectional liquid spreading mechanism on the peristome surface of N. alata, is explored and fabricated by two‐step UV lithography. Its superior unidirectional liquid spreading capability to that of other surface patterns is demonstrated, and its unidirectional liquid spreading mechanism...
A novel unidirectional liquid spreading surface inspired by the N. alata peristome is proposed and fabricated by H. Chen and co‐workers in article number 1601676, via two‐step UV photolithography. Its superior unidirectional liquid spreading capability is demonstrated, and the underlying mechanism of unidirectional spreading is investigated. This bio‐inspired surface will advance a variety of applications...
Solid electrolytes are one of the most promising electrolyte systems for safe lithium batteries, but the low ionic conductivity of these electrolytes seriously hinders the development of efficient lithium batteries. Here, a novel class of graphene‐analogues boron nitride (g‐BN) nanosheets confining an ultrahigh concentration of ionic liquids (ILs) in an interlayer and out‐of‐layer chamber to give...
V2O5 hollow microclews (V2O5‐HMs) have been fabricated through a facile solvothermal method with subsequent calcination. The synthesized V2O5‐HMs exhibit a 3D hierarchical structure constructed by intertangled nanowires, which could realize superior ion transport, good structural stability, and significantly improved tap density. When used as the cathodes for lithium‐ion batteries (LIBs), the V2O5...
Well ordered, uniform 3D open macro/mesoporous TiO2 hollow microspheres with highly crystalline anatase thin shells have been successfully synthesized by a simple solvent evaporation‐driven confined self‐assembly method. The 3D open macro/mesoporous TiO2 hollow microspheres show high energy‐conversion efficiency (up to 9.5%) and remarkable photocatalytic activity (with photodegradation of 100% for...
